The Sun Hydraulics RBAAJCN (RBAAJCN) is a direct-acting, pilot relief cartridge valve designed for precise pressure control in hydraulic systems. This valve is primarily used to remotely set the pressure of other pilot-operated valves, making it suitable for load-holding applications where maintaining consistent pressure is critical. The RBAAJCN model features a main stage orifice protected by a 150-micron stainless steel screen, ensuring durability and reliability in challenging conditions. It is important to note that back pressure on the tank port (port 2) directly adds to the valve setting at a 1:1 ratio, which users should consider during system design. This model can be configured with EPDM seals for compatibility with phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. The valve incorporates Sun's floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or machining variations. With a capacity of 0.5 gpm (2 L/min) and a maximum operating pressure of 5000 psi (350 bar), this cartridge valve is robust and reliable under high-pressure conditions. For ease of use, the RBAAJCN allows adjustment throughout its full range using W or Y controls unless specified otherwise with a special setting. The corrosion-resistant variants are available with external stainless steel components or zinc-nickel plating for enhanced durability in corrosive environments. With specifications including an adjustment screw internal hex size of 5/32 inches (4 mm) and locknut torque ranging from 80-90 lbf-in (9-10 Nm), this model ensures precise control and easy installation in various hydraulic systems.
